Is Google committing a crime if it indexes a CP site? Are you committing a crime if somebody links to CP in your blog's comments? Of course not. Having a link to something is not a crime.
The law recognises intent in most situations, and the Pirate Bay exists to provide access to expensive-to-create content without compensating the people who made it. Hence, they have problems (and justifiably so).
This is how they said Google was not guilty, but the pirate bay was (they mentioned Google specifically in the question and answer).
